Husserl’s Cartesian Meditations shows the role of phenomenology in the project of refoundation of sciences. Husserl exposed, starting from the Cartesian’s doubt, a solution to skepticism through an absolute foundation of knowledge. To do that, two things must be achieved: first, the main component of subjectivity, otherwise known as the “transcendental ego,” must be clarified to expose the essence of the subjectivity. Second, the intersubjective community, if properly constituted, should guarantee apodictic knowledge to phenomenology. This master’s thesis follows the development from the first reduction, which appears to refocus the phenomenologist’s gaze onto his own subjectivity, to the constitution of an intersubjective community. By showing methodically Husserl’s procedure, we will demonstrate how he develops a bona fide intersubjectivity, but also its epistemological limits. This examination will lead us to two things: first, the re-contextualization of what is a complex argument that is often reduced to a simple, classical idealism; second, the central role of the body, understood in a specific sense, in the Husserlian project, which should help to bridge the gap between what he called the different monads (subjects).
